To all whom t may concern:

Be it known that I, HARVEY F. MARAN- viLLE, a citizen of the United States, residing at Akron, in-the county of Summit and State of Qhio, have invented a certain new and useful Improvement in Lubricating Systems, of which lthe following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to systems for lubricating4 machinery and, in the particular embodiment shown herein, is designed with special reference to automobiles.

The apparatus disclosed herein constitutes a system by means of which the various parts of the engine of an automobile may be conveniently lubricated, a predetermined level of oil may be maintained in the engine base or crank case, sediment may' be automatically and conveniently removed from such base, and the surplus oil iiowing from the engine and from such base may be e'ec'tively filtered, washed and cooled, at the same time providing an arrangement whereby the quantity ofoil in the reservoir or tank may be conveniently and accurately indicated.

The object of the invention is to realize the above operations and results in an etlicient and economical manner; also to provide a particularly compact apparatus for this purpose which, as to certain features of construction is especially adapted for application to automobiles. y

Still further and generally speaking, the invention may be defined as consisting of the combinations of elements and parts embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein- Figure l represents a side elevation of a multi-cylinder engine having my invention applied thereto; Fig. 2 represents a vertical sectional view taken through the lower portion of a cylinder and crank case or base of an engine showing a part of my invention applied thereto; Fig. 3 represents a horizontal sectional view taken through the upper portion of the engine base, below the nate like parts in the different views, 1 represents the hood of an automobile and 2 the front wheel thereof. Beneath the hood and supported by the frame in the ordinary manner is the engine, shown herein as of 'the four-cylinder type, the cylinders being designated by the numeral 3. The cylinders are supported b a base comprising an upper casting or mem er 4 and a lower casting or member 5. The' upper member may be of ordinary type and is shown as provided with iianges 6 to which the lower member may be secured by means of corresponding anges 7 andbolts 8, the two members forming a crank case. Each cylinder is provided with a piston 9 of any standard construction, a piston of the trunk type being shown. A. Yconnectlng rod 10 extends between the plston and the crank 11, being connected to the latter in any approved manner.

.The lower section or member 5 is provided at lts lowest point with a preferably elongated opening 12 communicating with t.

a chamber 13 formed in a receptacle attached to the lower base section of the engine. The bottom 14, end 15, and sides 16 of this receptaclemay be conveniently cast with the bottom section 5, the receptacle being provided with a removable cover 17,

vwhich is shown as-provided at its inner edge with an upwardly projecting flange 18 by means of which 1t may be fastened to the engine base, as by screws 19.

The space within the receptacle 13 is divided into two or more compartments (two being shown) by means of a vertical partition 20 extending upwardly from the bottom plate 14 and having at its upper end a downwardly extending baffle plate 21. This partition divides the receptacle into -two chambers 22 and 23. The chamber 22 communicates with the lower'portion of the engine base or crank case by means of the elongated openings 12. The bottom of the receptacle 13 is conveniently cast with the bottom sect-ion 5, as stated, and is located below the same, being connected with the casing by means of a short vertical wall 2i which extends downwardl from the lowest portion of the discharge s ots 12. 'Each slot 12 is bounded on one side bythe junction of the Wall 24 with the lowest part of the lower section 5, the opposite side of the slot being formed by deiecting upwardly the portion of the lower section which is opposite such junction, as shown at 25, whereby each 'slot possesses considerable vertical, as well as longitudinal, extent. Each slot 12 -is so ar-y ranged as to be beneath a crank'pin .11 and is preferably co-extensive in length with the length of such crank pin. Each of these slots extends laterally from the center 0r lowest rticn of thel bottom sectionof the engine ase or crank case in the same direction in which the crank and connecting rod' vtached is ascending or descending a hill.

The outer wall 15 ofthe receptacle 13 is provided withV a filling tube 26, the upper end of which is substantially on` a level vwith the top of the partition 20. I

The compartment 22 is provided witha clean out opening closed by a plug 22a'. Through this opening the collected dirt may be readily removed from the chamber.

The compartment 23 is provided a-t its lower end with a pipe 27 extending to a pump 28, which may be .of any convenient type, being shown as rotary pump in Fig. 1 of the drawings. f i

The pump shaft 29 is shownas driven by means of a gear 30 meshing with a gear 31 on the engine shaft 32. ther driving means may be'used for the pump if desired. The outlet from the pump is connected by means of a pipe 33 with the casing 34 of my combined filtering, washing, cooling and storage tank. This pipe is conveniently threaded into the removable cover 35 of said tank. The tank is provided with an outlet pipe 36 conducting filtered and cooled oil-to a manifold 37, from which manifold pipes 38 extend to the upper portion of the engine base or crank case. The lower end 39 of each of'the pipes 38 projects through the wall of the upper section 4 of the crank case and` is preferably reduced in diameter so as to discharge oil in a tine stream or jet upon the. connecting rod journal as the rod revolves with the crank pin in the crank casing.

40 Vdenotes a gage which is connected by a suitable'pipe 41 with the casing 34 to indicate the level of the filtered oil in said casing. The chamber for filtered oil in the casing 34 is of the same capacity as the chamber 23 in the receptacle 13. Y n,

The details of 'construction of the filtering tank are shown,-described andclaimed in my application No. 569,459, filed lune 29th,

1910, which is a division of this application.

Lot/neas 'manifold 37 and pipes 38 into the engine base or crank casing. This oil is so directed as to strike the connecting rod journals and oil the parts. Oil accumulates in the lower portion of the engine base or crank casing until it reaches'the level maintained by the top of the partition 20. It there overiiows into the chamber 23, whence it is pumped by the pump 28 and the pipe 33 into the filtering, washing and cooling tank.

Carbon and other sediment accumulate in the bottom of the crank case. Owing to the location and arrangement of the slotted ports or apertures 12 in the sediment chamber 22, the sediment is swept out of the crank case Aby the revolution of the cranks and carried into the chamber 22, whence it may be conveniently removed by taking ofi' the cover 17. The baille 21 prevents the sediment from being carried over the partition 20 and into the chamber 23.

Among the objects of my invention are the constant supply of clean, cool oil in ample quantity to the places where needed; the positive removal of the sediment from the oil in the crank case through the operaobserve at all times the condition of the oil in the system; and the ability to replenish the oil, as exhausted, by means of the filling tube 26. A further and marked advantage in the automobile art is the adaptability of my system for all incidents of use. The substitution of the lower section of the ordinary crank case or engine base by the corresponding parts of my invention can be made conveniently and at comparatively small expense, while the distance usually provided between the engine base and the side frames of automobiles is amply sufficient to accommodate the receptable containing the sediment and filling chambers.

In practice' the outlet pipe 36 is of less capacity than the pipe 33, a convenient size for these pipes being il inch for the pipe 33, and si inch for the '.pipe 36.

Furthermore, the construction of the attachment to the engine `base insures, at all times that the gage 40 showsthe maintenace of oil at the proper level in the engine base for lubricating purposes.

In the specificatlon and claims, reference is made to the crank dipping into the oil in the crank case in order to lubricate by the splash system and sweep the sediment from the case into the chamber provided for the sediment. By the term crank I do not propose to be limited to any special part of the crank shaft or the cooperating portions of the connecting rod, it being suliicient for the purpose of my invention that any of the parts rotating with the crank shaft dip into the oil and sweep out the sediment as'd'escribed.
